For every 3/4 of an hour Saul studies Spanish, he spends 1/5
1 answer:
Answer & Step-by-step explanation:
The fraction 3/4 can also be written as 0.75. The fraction 1/5 can be written as 0.2. So, we can find the unit rate of the time Saul spends studying French to the time he spends studying Spanish by dividing 0.2 from 0.75.
0.75 ÷ 0.2 = 3.75
So, the unit rate of the time Saul spends studying French to the time he spends studying Spanish is hours.

Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
<u>Solution:</u>
Need to determine what operation is required to get one-tenth of a number and 10 times of a number
To get one tenth of a number, divide the number by 10.
For example to get one – tenth of 100, divide it by 10, we get 10 as a result.
To get ten times of a number, multiply the number by 10
For example 10 times of 10 = 10 x 10 = 100
Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
Answer:
0.756
Step-by-step explanation:
It is given that a machine has four components, A, B, C, and D.
If these components set up in such a manner that all four parts must work for the machine to work properly.
We need to find the probability that the machine works properly. It means we have to find the value of .
If two events X and Y are independent, then
Assume the probability of one part working does not depend on the functionality of any of the other parts.
Substitute the given values.
Therefore, the probability that the machine works properly is 0.756.
